Member Function Documentation

◆ Begin()

void TSelEventGen::Begin ( TTree )
virtual

The Begin() function is called at the start of the query.

When running with PROOF Begin() is only called on the client. The tree argument is deprecated (on PROOF 0 is passed).

Reimplemented from TSelector.

Definition at line 66 of file TSelEventGen.cxx.

◆ GenerateFiles()

Long64_t TSelEventGen::GenerateFiles ( const char *  filename,
Long64_t  sizenevents

Generate files for IO-bound run Input parameters filename: The name of the file to be generated sizenevents: Either the number of events to generate when filetype==kPBFileBenchmark or the size of the file to generate when filetype==kPBFileCleanup Returns Either Number of entries in the file when filetype==kPBFileBenchmark or bytes written when filetype==kPBFileCleanup return 0 in case error.

◆ Init()

virtual void TSelEventGen::Init ( TTree tree)
virtual

Reimplemented from TSelector.

◆ Notify()

virtual Bool_t TSelEventGen::Notify ( )
virtual

This method must be overridden to handle object notification.

Reimplemented from TSelector.

◆ Print()

void TSelEventGen::Print ( Option_t option = "") const
virtual

This method must be overridden when a class wants to print itself.

Reimplemented from TObject.

Definition at line 487 of file TSelEventGen.cxx.

◆ Process()

Bool_t TSelEventGen::Process ( Long64_t  entry)
virtual

The Process() function is called for each entry in the tree (or possibly keyed object in the case of PROOF) to be processed.

The entry argument specifies which entry in the currently loaded tree is to be processed. It can be passed to either TTree::GetEntry() or TBranch::GetEntry() to read either all or the required parts of the data. When processing keyed objects with PROOF, the object is already loaded and is available via the fObject pointer.

This function should contain the "body" of the analysis. It can contain simple or elaborate selection criteria, run algorithms on the data of the event and typically fill histograms.

Reimplemented from TSelector.

Definition at line 327 of file TSelEventGen.cxx.

◆ SetInputList()

virtual void TSelEventGen::SetInputList ( TList input)
inlinevirtual

Reimplemented from TSelector.

inlinevirtual

Reimplemented from TSelector.

Definition at line 66 of file TSelEventGen.h.

◆ SlaveBegin()

void TSelEventGen::SlaveBegin ( TTree tree)
virtual

The SlaveBegin() function is called after the Begin() function.

When running with PROOF SlaveBegin() is called on each slave server. The tree argument is deprecated (on PROOF 0 is passed).

Reimplemented from TSelector.

Definition at line 90 of file TSelEventGen.cxx.

◆ SlaveTerminate()

void TSelEventGen::SlaveTerminate ( void  )
virtual

The SlaveTerminate() function is called after all entries or objects have been processed.

When running with PROOF SlaveTerminate() is called on each slave server

Reimplemented from TSelector.

Definition at line 460 of file TSelEventGen.cxx.

◆ Terminate()

void TSelEventGen::Terminate ( void  )
virtual

The Terminate() function is the last function to be called during a query.

It always runs on the client, it can be used to present the results graphically or save the results to file.

Reimplemented from TSelector.

Definition at line 481 of file TSelEventGen.cxx.
